Day 24: Macro Nutrients

Today, I woke up and weighed myself. Weight is: 83.4Kg. Yesterday I consumed 103 calories below my BMR and did 305 calories of exercise above my BMR. Total deficit is 408 calories.


The food we eat can be classified into three different types: Proteins, Carbohydrates, and Fats. These are also called macro nutrients and are the foundation of our nutritional needs. The purpose of a food guide is to help people eat the right foods in the right proportions to stay healthy. Presumably, using a food guide to build a meal plan will allow a person to get all the nutrients they need and ensure their caloric intake remains at a point where weight gain will not occur.


Proteins are very complex chemicals (yes, everything we eat, in the end, is a chemical) made up of Carbon, Hydrogen, Oxygen, and Nitrogen. These are the building blocks of all the cells in our body, and the body uses Protein to rebuild itself. Proteins are the body’s last resort for energy.


Carbohydrates are made up of Carbon, Oxygen, and Hydrogen (pretty much the same stuff as petroleum). The body uses Carbohydrates as it’s first source of energy.


Fats are complex chemicals also made up of Hydrogen, Carbon, and Oxygen (HydroCarbons). They are used by the body for energy, plus many other important functions.
